Czsmbt CV40 Carburetor for Harley-Davidson Sportster 883/1200 (1988-2006) - Direct-Fit with Tune-Up Kit

The Czsmbt CV40 Carburetor is a ready-to-install replacement carburetor and tune-up kit engineered to restore throttle response and fuel delivery on Harley-Davidson Sportster, Dyna, FXR, Touring and Softail models from 1988–2006.

Built as a direct-fit replacement for many factory part numbers, this CV40 assembly arrives with choke cable, spark plugs, extra main and pilot jets, a fuel filter and a brush set so you can perform a thorough carb rebuild or swap without sourcing parts separately. It matches stock jetting (main #170, slow #45) out of the box and includes additional jets for simple tuning to match altitude, performance upgrades, or fuel differences.

Will this carburetor fit my Harley-Davidson model?

The CV40 is designed to replace a long list of OEM part numbers and fits numerous Harley model families produced between 1988 and the mid-2010s. Confirm compatibility by comparing your bike's year and existing carb part number against the supplied fitment list.

• Fits Sportster 883/1200 models (XL883, XLH883, XLH1200) 1988–2006
• Compatible with Heritage Softail, Dyna, FXR, and many Touring models 1988–2016/2017
• Replaces multiple OEM numbers such as 27031-95, 27412-99, 27490-04, and others listed

How does the included tune-up kit simplify installation?

Instead of buying parts separately, the package gives you the common consumables needed during a swap or rebuild. That reduces downtime and ensures you have the fittings and jets to fine-tune mixture and idle without a second parts order.

• Comes with choke cable, two spark plugs, brush set and fuel filter
• Extra main jets (#180, #185, #190) for richer mixtures when required
• Extra pilot jets (#42, #45, #48) to adjust idle and low-throttle response

What jetting and starting settings should I expect out of the box?

The carburetor ships with the stock jetting typically used on compatible Harleys: a #170 main jet and a #45 slow (pilot) jet. Those settings provide a baseline for most standard engines, and the included spare jets let you adapt to mods or regional fuel variations.

• Factory-installed main jet: #170
• Factory-installed slow (pilot) jet: #45
• Included spare mains and pilots permit richer or leaner adjustments as needed

What support and warranty come with this carburetor?

The product is sold with a one-year service window and the option for refund or replacement if you are not satisfied. Keep your receipt and contact the seller for troubleshooting, parts replacement, or return instructions.

• One-year service coverage from date of purchase
• Refund or replacement available for buyer satisfaction issues
